Lexus GX 2004-09 :: 2005 - VSC / Trac Off Lights Came On?
Sep 29, 2011
I bought my wife a 2005 Gx470 this past weekend. She has only driving it for the past 2 days. (still had gas in the old car, which is now for sale) She called me and said the VSC light off light came on and the Trac light was on. I did some quick searching and couldn't find anything definitive on what or why the lights came on for. She got gas yesterday, but probably only drove about 40 miles. I asked her if she tightened fuel cap until it clicked, she said she thinks...(crazy pregnant woman).
I'm trying to avoid a trip to a dealer on a car I bought 5 days ago. Also, how to reset the codes without a computer? I know my GMC truck, I just unhook the battery for 30mins or so and clears all codes. Hoping Lexus has a cheat too

SO all three lights came on and wouldn't go away.
Ran a scanner for code and got p0430.
Took it dealership for estimate or fix.
Go figure : code summary: Causes.
Reported fixes or Causes: for code p0430
- catalytic converter has failed.
- Air fuel ratio sensor
- Bank 2 cat converter
- Bank 2 (A/F) ratio sensor
- Oxygen 02 sensor
- downstream Oxygen 02 sensor
- Exhaust pipe
- Mass Air flow sensor
So I am waiting thinking ok let be one of the above causes or fixes that is cheap.

This is happening intermediately, maybe 1 out of every 5 starts.
Using the override I can shift just fine and the lights go away within 2-3 minutes. However, there's obviously something misaligned here. Search revealed potential brake switch issue (my tails and brake lights are fine so no issues there), lockout issue, or a park neutral switch.
So I took the panel apart and I am trying to isolate these potential issues, image attached, what I need to do next? I am more of a visual person so if someone can circle the part I need to disassemble or replace that would be most useful.

Tonight, during a short ride, all the sudden the VSC TRAC, VSC OFF and Check Engine came on. Atfter home, I got the P0057 code from a OBDII scanner. The P0057 code indicates O2 sensor on bank 2 lower sensor. However, the interesting thing is I also lost the power seat adjustment on the seat memory. When I switched between L1 and L2 , the mirrors and the steering position changes and the seat did not. However, the adjustment buttons on the seat itself work correctly. I wonder if this problem associates with P0057?

I have a 2005 Century that show ABS and No Trac warning lights. I use an electrical cleaner spray (without lube) on the front passenger side ABS connector spraying male & female ends. The warning lights don't reappear and brakes seem to function normally.
Then a few months later the same warning lights appear, I repeat the spray and everything seems to return to normal again. This process has been going on for about a year.

Engine light, VSC and TRAC off lights come on. Local garage says code P1201, go to transmission shop. My code book says Injector circuit open/shorted cylinder #1. Is this still a transmission shop issue? I am terrified of dealerships, can I drive it a few more days, short distances whilst I decide who will dupe me over more?

Must have pushed the wrong button in the dark. Anyway, the TRAC button and the check engine light both lit when I started the car. (push button start). How can I get it off??

This is a new phenomenon for me and from what I have read it could be the emissions system, gas cap or Catalytic. Clearing the codes only brings the lights back on when I put the car in drive or reverse. I know I can replace the gas cap (cheap) Replace the catalytic ( more expensive - since the exhaust has a rupture in the braid) and have the emissions sensor replaced (marginal cost)....

All other lights work including Driving lights and High Beams.
I have checked fuses.

I've got an 01 Tundra with 170k and no trouble. And a 01 Highlander 4 cylinder with 330K and no trouble. We just added a 04 RX330 with 170k on it. It had an impeccable 15 page Lexus dealer history.
That said, I had the check engine, Trac off, and VSC light come on about a month after we bought it. I used my acton scanner cleared it out. Then I noticed the gas cap was loose so I attributed the issue to that.
Yesterday, the lights came back on again. I have not cleared the code this time. My scanner is showing a "P0420 Catalyst Efficiency Below Threshold Bank 1" error. This car has a brand new cat installed by the Lexus dealer about 6 months ago.
I saw the buttons below the dash that say Trac off on them.

All of these lights came on for no apparent reason. I check with computer based OBD reader, and I'm getting code P0049 (Turbo/Super Charger Turbine Overspeed). Weird code considering the lack of turbo or super charger on the GX. I cleared the codes, but all came back after a few miles of driving. What code P0049 is pointing to? My truck is 04 GX470 with 74,000 miles.

I have a 2007 RX350 and these lights come on intermittently --> TRAC & VSC LIGHTS ON. ALSO ABS, BRAKE LIGHT. When I turn the car off and on again they would disappear. So I cannot take it to Autozone (For code read) because the problem goes away when car is shut off/on.
I believe it is tied to the front brakes which are new but the steering wheel shakes when braking. I had the rotors turned a year ago and it seemed to have fixed the problem but now the shakes are back and so is the light problem.
This makes me think that there is a loose connection (Wire / connector) around the front brakes.

08 RX350 with ~100K miles. Two weeks ago the Check Engine/TRAC light were on, VSC light blinks, so I tightened the gas cap, and pull the negative and cleared the code. Hoping this is just a gas cap issue.
2 weeks later all those lights are back again, so my mechanic pulled the code and came up with P0128. He told me it should be the problem with the Coolant Temperature Sensor. The water pump, thermostat was replaced last year and coolant level is OK. No issue with coolant temperature and the car drives like normal. My mechanic cleared the code and told me to drive it again until the lights come back and he will pull the code again.

I've had this 2003 XLE v6 for several days. Just got new rear tires, to match the almost new fronts.
Drove fine for about 100 miles. Then my conscience told me to get an alignment. I got in the car after the alignment and the VSC and TRAC OFF lights were on. I went back in and got the "they were on when we drove it in" song.
After pressing the trac button several times, the VSC went off, then the TRAC OFF when out. "Oh well" maybe he was not BSing me, so I drive off. Came back on within a couple hundred feet.
Now, it seems they go off right after starting the engine, with all the others, but will come on almost as soon as I drive off. If I just sit there idling, does not seem to come back on.
I should add they also told me the cabin air filter was filthy and had to wait while the put it back in when I declined. After all, I can get it way cheaper, etc. I mention because I have seen some comments about this happening in some models after changing that filter.
So, what did the do? Or what can I do?

03 xle 3.0. Recent motor mounts, front lower control arms, LR bearing. All good. Raining. Driving around all good. Stopped for several hours, started up, immediately brake vsc, trac, abs came on. Stopped to get a sandwich, started up again, all are out. Car seems fine otherwise.

2003 Camry XLE V6.. As soon as I drive the VSC an TRAC OFF lights go on.
This happened recently: Had low air pressure on rear driver's side tire. Gave it air and it's good now.
The lights still won't turn off. I took it to a mechanic, he checked on the computer, but found no codes. I told him about the deal with the tire and he said that the system might need to be reset or re-calibrated because the stability control probably detected one of the tires had some abnormal movement by hitting a bump or maybe because of the low tire pressure, etc.
How do I reset/re-calibrate or do whatever to turn these lights off?

2003 Camry xle 3.0 auto. VSC and trac off lights came on after I plugged in an obdc II checker. A 30 dollar red one.
This happened once before when I had a wheel alignment done but kept pestering the shop till they fixed it.
This time, I had the rr jacked up to look for source of noise and plugged this in, just for chuckles. No chuckles now.
I did find a write up on how to turn it off with some paper clips and fancy finger work and will give it a go.
But, is this going to happen every time I plug in a tester?

Why are my ABS and Trac lights going on and off periodically?

I have recently purchased a low mileage 2006 Scion XB and have had to have a faulty front ABS senor replaced at a local repair shop. The mechanic used a "genuine Toyota" replacement sensor. After a couple of miles my ABS light along with the TRAC and VSC lights came on. He reset the computer and they came on almost immediately. His computer read faulty ABS sensor, he said that he checked the new sensor and it worked. He sent me to Toyota, who also diagnosed it as faulty sensor and when they checked the sensor it was fine.
They said the problem was rust, cleaned the sensor and hub and everything was fine for about 50 miles, then the lights came on again. The service manager said that if the problem came back that they would have to replace the front hub. Can I again clean the sensor and hub myself? I have a bead blaster would that likely clean it enough? Would coating the cleaned metal with something like a really light oil (like WD 40) to stop the rusting? And lastly, if I am successful in cleaning it all does the computer need to be reset or will it reset itself? I have some skills, have done brakes, replaced engines and stuff like that.

I have a 2007 Toyota Camry LS that says check vsc system. The check engine light, vsc and trac lights are all three are on. That is a concern but another big concern is that is sometimes runs sluggish and acts likes it wants to stall. ?

2001 Alero ... I've read about the sensors and wiring on the hub causing the ABS and Trac lights. They come on with the Service Vehicle Soon light, sometimes, when I start rolling.
I had a mechanic look at it, and it was not giving any codes. He tried to turn off the lights with the machine, and they would not turn off. He concluded that it was a computer problem. He said that a ground causes the lights to come on, so it could be a wiring problem.
Why would my lights come on intermittently? Do I have to wait until they come on, then immediately pull over and check the sensor or hub? Is there any way to check this on my schedule?
